29、s and protective conductors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions conce
30、rning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Thei
31、r preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates c
32、losely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the rel
33、evant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the
34、 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximu
35、m extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies pr
36、ovide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC o
37、r its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expen
38、ses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Atten
39、tion is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60364-5-54 has been prepared by IEC technical committee 64: Electrical i
40、nstallations and protection against electric shock. This third edition cancels and replaces the second edition, published in 2002, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: clarification of the definition of protective conductor; im
41、proved specification of mechanical characteristics of the earth electrode; introduction of earth electrode for protection against electric shock and lighting protection; annexes describing concrete-embedded foundation earth electrodes and soil-embedded earth electrode. The text of this standard is b
42、ased on the following documents: 60364-5-54 IEC:2011 5 FDIS Report on voting 64/1755/FDIS 64/1766/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. It has the status of a basic safety publication in accordance with
43、 IEC Guide 104. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The readers attention is drawn to the fact that Annex E lists all of the “in-some-country“ clauses on differing practices of a less permanent nature relating to the subject of this standard. A list o
44、f all parts in the IEC 60364 series, under the general title: Low-voltage electrical installations, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.
45、ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60364-5-54 IEC:2011 INTRODUCTION Clause numbering is sequential, preceded by the number of this Part. Numbering of figures and tables takes
46、the number of this part followed by a sequential number, i.e. Table 54.1, 54.2, etc. Numbering of figures and tables in annexes takes the letter of the annex, followed by the number of the part, followed by a sequential number, e.g. A.54.1, A.54.2, etc. 60364-5-54 IEC:2011 7 LOW-VOLTAGE ELECTRICAL I
